lBe 1t known that l, BURNILUL C. H'ricii- Nm', a citizen of the UnitedStates, residing in Elizabeth, in the county of Union and State of NewJersey, have invented certain new and useful Improvements in TyperritingMachines, of whichthe following is a. specification.

'lhis invention relates to the line-feeding mechanism of t.}-pcw'ritingmachines; and one of its main objects is to provide. simple, compact andinexpensive means for elteeting adjustments of the platen otherwise thanblv the usual line-spacing lever; and particulaly to provide simple andconvenient means for turning the platen through relatively greatdistances bacluvardly and t'o'rwardly for condensed billing.

Another object is to provide suitable means for advancing the platenautomatically to vproduce a blank' line between entries on the carbonsheet.4

Another object. is to enable the mechanisln to be used also forettecting tine adjustments of the platen.

ln the accompanying drawings, Figure 1 is a plan of a typewritercarriage provided with one form of my improvennnts. Fig. E?. is a-Seetional detail of a lever provided with a sliding line-spacing pawl.Fig. 3 is a seetional end elevation of the line-spacing mechanism. Fig.4 is a sectional t'ronty elevation of the devices seen atlFig. l,omitting the casing in which the line-spacing mechanism is inclosed.Fig. 5 is an' end ele-:ation of the devices seen at Fig 1', the platcnyaxle being shown in section. Fig. 6 is a plan ot' a cam collar, showingpart of the means For automatically advancing the platen while themachinevis used for condensed billing. Fig. 7 is a plan of a. rotatablehead, which is to receive the crank seen at Figs. 1 and 5, and whichalso is intended to-carry certain of the line-spacing devices. Fig. S isa plan ot' a sliding collar by which movement. is transmitted to theline-spacing devices.

ing endwise displacement of the axle and platen. Upon the axle withinthe platenframe and at the lett-hand end of the platenframe is secured aline-space ratchet wheel l1, by means of a hub 12 and screw 13, theratchet-teeth V1-1 being upon .the outer face of vthe wheel.Line-spacing mechanism adapted to said ratchet wheel is mounted upon arevoluble head, comprising a hollow .shaft 15 having atits inner endnear said i'at .'l|et-\ vl1eel opposite bent'arms 1G and 1T; said shaftat its outer portion being journaled in the side-har 3 ot' theplaten-trame, as at 1S, and being hollow to /alford a bearing for theplaten-axle 5 which extends .entirely through the same.- Saidline-spacing mechanism comprises a lever 19, hinged at. and 21 uponreflevly bent cross-arms 32 and 23 secured upon said revoluble head; thepintle ot' the hinge being designated as 24, and said lever havingtheform of a bail which embraces said bearing arms. Upon one end of thelevel' is formed a cylindrical housing for a sliding pawl QG. providedwithin' the housing with a eonn'iression spring 27 coiled about; a stem28 formed upon the pawl. said stein being provided with a cap 2S) tolimit the projection 'of the pawl froin the housing. As seen at Fig. 1.the pawl stands normally clear of the linespace ratchet wheel` so that'the platen may be freely rotated b v either linger-wheel or 7; while bymovement about the axis 2l, the pawl may be swung into engagement withthe ratchet-wheel to rotate the same. Upon the end of an arm 30 alsot'ormed u )on said revoluble head, `is pivoted at 3l a detent. in theform of a lever, one arm 3; whereof earries a roller 33 which engagesthe notches in the ratchet-wheel` while the other arm S-t is connectedby a. draw-spring 35 to an arm 36. the latter forming an extension ofonel of thc bail-arms of the lever 19. The spring thus serves thetwo-fold purpose of applying pressure to the detent and returning saidlever to normal position after actuation.

v1t will now be perceived that the platen may be rotated. by ,either ofits fingerwh'eels. or given a line-space mevement by the lever and pawl;and that it is always held against accidental rotation by the de-y tent;and also that byrotating the revoluble head, together with the lever.pawl and dctent thereon, the latter carries with it both theratchet-wheel and platen; whereby exceptional rotative adjustments ofthe platen may be effected, together with kthe paper thereon, therebyfacilitating writing upon ruled lilies, making corrections, etc.; whileat all positions to which the head may be adjusted, the lever and pawlmay be operated to effect the line-spacing movement of the platen. Forrotating said head, a crank 3T is provided upon the end thereof thatprojects from the laten-frame; and for holdin olution a' 'alte isemployed, coniprising a spring 38 housed in the end 3 of the platenframe and bearing against a plug 38 loose in the same bore 38h whichconfines the spring, and pressed by the latter against the -journal ofthe rotated head 15;said journal being enlar ed in diameter to increasethe friction, an a4 shoulder 89 being formed at the inner end of saidjournal to prevent displacement of said head toward the lefft. Thetension of the spring 38 may be regulated by a screw 38C; said springbeing sufliciently powerful to hold the revoluble head steady at theline-spacing operation, and being considerably superior in elficiencytothe detent 32, so that the resistance of the latter may be overcomewithout stirring the revoluble head.

A line-spacing lever 40, consisting of a curved finger-piece 41 and amain forked portion 4.2, which bestrides the front carriage-bar 1 andthe platen axle, is mounted upon avertieal pivot 43 in rear of theplaten axle, and is adapted to swing from normal position toward theright at. Fig. 1, or in the direction of the return movement. of' thecarriage. The connection between said carriage lever and thepawl-carrying lever-19 which mounted upon the revoluble head. comprisesay sleeve 44, spli'ned by 11u-.ans of' .pin and slot 4G to the tubularmember la 45,017 said revoluble head; said Isleeve, having at its outerend a shoulder t7 engaged by opposite pills 48, 4t) fixed upon thelinespacing lever 40, and having at its inner end a pin 5() engaging aradial lslot 5l formed in `a spur 52 formed upon the lever lt. By meansof the spline, the sleeve Ll-Jf is caused to rotate with the revolublehead. but may move therealong, the latter movement being effected by thepins 48, 19 and annular shoulder 47, so that. the carriage lever il()may effect a movement of the. lever 1t) at. any point towhich therevoluble head may be adjusted, and thereby etl'ect a line.sp:ic ing orstep-by-step rotation of'- the. platen. It will be seen that the pawl2G, which is -normally out of engagement with the lines'paeewvheel, topermit the platen to be rotated by hand freely in either direction. isswung into engagement. with the ratchetwheel by means of theftinitialmoven'xent ot' the head a-galnst accidental rev` `throw of the platen.

'sleeve may be adjusted along the bar,l and is provided on its upperlside with a projection 54, adapted to be inserted in any one of a seriesof three holes 55 formed in a yielding keeper 5G, the latter beingsecured to the carriage bar a screw' 57and provided at its freeoverlying end with a `finger-piece 5S, whereby it may be raised clear ofthe pin 5l. The lever 4() will throw one, two or three line-spaces,according to theadjustlnent ot'.

the sleevestop 53.

It will be perceived that the spring $15, which controls theratchet-wheel detent, serves also by reason of itsI connection vtoan armof the lever 19, to return the latter to normal position afteractuation, together .with the sleeve 44 and lever -.'l-1. 1t will befurther understood that during the lines acin oeration the swine` ot'the arm Bti" n vis sufficient 'to increase the tension of the springmaterially, whereby the detent roller 33 is pressed with great forceagainst the ratchet-wheel at the completion of 'the line-spacing stroke;and consequently the increased effectiveness of said detent aty thismoment may be relied upon to prevent. ovm'- That is to say, the pressureof the detent may be normally so slight as to permit free rotation ofthe platen by the hand-wheels (i and l', butmay by the described meansbe rendered so powerful aty the completion of the line-spacing movenlentof the platen as to jn'event its overthrow. l

As illustrated at Figs.- '1 and il, a cylindrical easingor' drum 5E) mayincase.; the ratchet# wheel, the rmfoluble head and the parts thereon toprotect the parts'l'rom injury and to contribute tothe neat and compactappearance of the nmchine. which has a handle (10, is formed upon itsopposite sides," with a series of notches or teeth (i1. which #form adouble rack. stop (i2 is formed to bestri'de'the crankand slip into `thenotches and may be adjustable along the crank. Upon the platen frame issecured by screws (33 ay plate G4 having thereon a of facets (l5 to beengaged by the stop (i2 to liln'it the initial stroke of the crank andplaten. These stops form a volute series, being located successively atincreasing distam-.es from the platen axls` 5 to correspond with thelocationof the notches't'il on the crank 17. Then it'y is desired tohave the stopl G2 engage with the ios first stop 65, the stop 62 isplaced in t'he first pair of notches, as shown at l. ig. 5. The stopsare placedat'angular intervals agreeing with those of the teeth of t-heline-space Wheel 11; and when it is desired to turn the platenbackwardly from the normal Fig. 5 position to an extent greater by oneor more line spaces, the stop 62 is adjusted to the second, third,fourth or other notch as t-lie case may be. By adjusting the stop to thetop notch, a movement of the crank and platen is permitted about fourfifths of a revolution from normal position. The invention is notlimited to this construction of stops or `adjustment. The handle 60 is pgrasped, and the platen swung .backward l formed in the platen frameend.

outer-end, it bears against the shoulder 47 thereby toa point determinedby the previous adjustment of the stop 62, and then. the

'Written bill is removed from the machine,

and a fresh bill blank substituted; the record and carbon sheetsremaining in the machine, as usual in condensed billing. Then the handleis' grasped and the platen turned forwardly thereby', until arrested bya stop 66 projecting from the plate 64 in the path of a lug 67 formed onthe hub of the crank 37; said stop 66 determining vthe initial or normalposition of the crank.

It will be seen that the crank remains stationary during the linebyline'movement of the platen effected by the lever 42 or the platenknobs 6, 7. At any time the handle 60 may be grasped to rotate theplaten through the detent 33.

`The .automatic'adva-nce of the platen to produce a blank space betweenbill entries on the record sheet is effected by means of a face orhelical cam 68 formed up'on a collar 69, which is secured by screws 70to the head 15, said collar 69 fitting the hub of the crank 37 and theside of the platen frame end 3, to prevent displacementof said headtoward the right. Said cam 68 engages a horizontal thrust pin 70, whichextends parallel with the axis 5, and is mounted for a sliding movementin a perforation 71 At its upon the sliding collar 44. When thereforethe crank is swung over forwardly to give the initialV rotation to theplateii',the cam 68 forces the pin 70 tor the left at Fig. 1 togetherwith the collar 44, and the line-spacing lever 19 is vibrated intoengagement with the line-space wheel, andthe latter is accordinglyadvanced one or more notches according to the form and extent of the cam68, thus producing' a blank space between entries on the carbon sheet.During the return stroke of tliefcrank'37, the collar 44 is returned tonormal position by the spring 35 together with the pin 70.

When desired, the screw 70 may be unscrewed torelease the collar 69, sothat the platen may be turned Without affecting the paper; and thecrank- 37 may be then used `adjustment of the crank or other driver 37.

'frame t0 turn coiiccntrically vments mounted on tl e platen and theother automatic advance feed of thc platen and freely for efl'ectingineadjustments in the position of the platen and the paper, for writinguponruled lines, and other purposes; -and when desired the stop 66 may bedetached. The lever 42 may always be used to line-space the platen,regardless of the Variations may be resorted to within the scope of theinvention, and portions of the improvements may be used without others.

Having thus described my invention, I
